Diagnostic Reasoning with Multilevel Set-Covering Models
نویسندگان
چکیده
We consider multilevel set-covering models for diagnostic reasoning: though a lot of work has been done in this field, knowledge acquisition efforts have been investigated only insufficiently. We will show how set-covering models can be build incrementally and how they can be refined by knowledge enhancements or representational extensions. All these extensions have a primary characteristic: they can be applied without changing the basic semantics of the model.

Single Assignment Capacitated Hierarchical Hub Set Covering Problem for Service Delivery Systems Over Multilevel Networks
The present study introduced a novel hierarchical hub set covering problem with capacity constraints. This study showed the significance of fixed charge costs for locating facilities, assigning hub links and designing a productivity network. The proposed model employs mixed integer programming to locate facilities and establish links between nodes according to the travel time between an origin-...
متن کاملMultigranulation single valued neutrosophic covering-based rough sets and their applications to multi-criteria group decision making
In this paper, three types of (philosophical, optimistic and pessimistic) multigranulation single valued neutrosophic (SVN) covering-based rough set models are presented, and these three models are applied to the problem of multi-criteria group decision making (MCGDM).Firstly, a type of SVN covering-based rough set model is proposed.Based on this rough set model, three types of mult...
متن کاملA New Inference Method for Frame-Based Expert Systems
This paper introduces a new frame-based model of diagnostic reasoning which is based on a generalization of the classic set covering problem in mathematics. The model directly handles multiple simultaneous disorders, it can be formalized, it is intuitively plausible, it provides an approach to partial matching, and it is justifiable in terms of past empirical studies of human diagnostic reasoni...

متن کاملIncremental Development of Diagnostic Set-Covering Models with Therapy Effects
We will consider set–covering models for diagnostic tasks handling uncertain knowledge. Because these models have to be build manually by domain experts, we will show how this effort can be reduced by an incremental development of the set–covering models. Thus simple models can be enhanced by similarities, weights and uncertainty to increase the quality of the knowledge and the resulting system...
